The issue isn't that R2 supposedly contradicts R1. Nobody thinks it does, not even Popper. Popper's whole falsificationist program is saying that "con...

Correct so far. Not so correct according to a falsificationist like Popper. A claim being scientific has nothing to do with whether it is true or not:...

The pursuit of wisdom. Wisdom, in turn, does not merely mean some set of correct statements, but rather is the ability to discern the true from the fa...

Can I color it both pink and invisible?

I think philosophy is much like martial arts for the mind: as the practice of martial arts both develops the body from the inside and prepares one to ...

Nobody is saying black things EQUAL ravens. Black things are a SUPERSET of ravens; at least, that's the claim in question. That claim might be false; ...

Take a look at this image: https://uploads.desmos.com/activitybuilder/722f70e4dfcd9e0c9e174fc45a22c1f4 Everything in B is in A. Everything that is not...

It does. We can symbolize "all ravens are black" as "R -> B". That's equivalent to "~(R ^ ~B)" or "~R v B" or "~B -> ~R", which we would say as "nothi...

It couldn't, which is the point. Confirmationism implies that it could, which is absurd, hence disproving confirmationism.

Nope, it's falsifiable by finding a non-animal that is a cat. "All cats are animals" = "if cat then animal" = "not (cat and non-animal)" To falsify it...

Hypothetico-deduction is confirmationist, not falsificationist.

I just added to the OP this for clarification of the intent behind this poll: The impetus behind this question is reflecting on how at different stage...

Is your username "A Seagull" because you're just here to shit on everything?

I think you understood my example backwards. This isn't about you or me arguing with a creationist. This is about what if you or I are like the creati...

That is my usual approach, which is what makes circumstances like this interestingly problematic to me: when I can’t follow the line of argument, but ...

Other way around: knowledge is a form of belief. Justified true belief, traditionally, but it's recently come into question whether that is enough. Bu...

This isn't meant to be passive-aggressive toward him, I don't have any problem with him personally, and it's not just about him. I genuinely thought t...

I find it interesting that this thread has been derailed into exactly one if the examples of this phenomenon I had in mind (math proving things about ...

Kant was using what contemporary philosophers would consider slightly ambiguous language. "Predicate" is a linguistic term, and existence is certainly...

First question lacks the reasonable answer: housing is ridiculous overpriced (due largely to rent-seeking activity on the part of the rich). Even aver...

Art is anything presented bu an artist to evoke a reaction in an audience. No qualities of the thing presented or the kind of reaction evoked or the c...

Are there true sentences involving colors as objects of them? If so, then colors exist.

Murder is a subset of killing, not an alternative.

I didn't create this thread to talk about one specific argument, but more about the general type of question that an argument that I've seen repeated ...

We can always just rephrase it as the Paradox of Gentle Killing and still have the same formal problem to sort out. It actually works out a little bet...

I don't really want to share a specific example because I don't want to cause drama calling out the main person I've encountered this phenomenon with....

I'll be voting Bernie in the Democratic primaries, but probably whoever wins the Green ticket in the general (living as I do in California; if you liv...

Now suppose that Russell, who you probably trust to be a lot better at you than math, claimed that he could mathematically prove, with math too comple...

I'm not sure what you're saying here. "Cisgender" is to "transgender" as "heterosexual" is to "homosexual". What's the problem? It can mean both: The ...

"Cis" is short for "cisgender", the opposite of "transgender". "Cis" and "trans" are generally Latin prefixes meaning "on the same side as" and "acros...

I intentionally picked two things that seem like a huge mismatch to me, because when I encounter this phenonemon in person the field of the premises a...

Looks good enough for me. :)

The logic as Forrester interprets it means that every murder that was ever done, ought to have been done. That seems like something has gone wrong in ...

I don't see why it would be a tautology. As to whether that could be a workable basis for a normative ethical theory, that would depend entirely on ho...

I think that last bit has some small errors in the explanation of ?A?B(?x(x?A?x?B)?A=B), and it might be clearer to switch the places of the biimplica...

In my philosophy I set out to do something very similar to this. I start out with rejecting two positions that I call fideism and nihilism, the latter...

Somehow I missed your post earlier. You make a good point about my formalization of "you murder gently" as a conjunction of "you murder" and "you are ...

Yeah, I mentioned that upthread, in my second post. That is correct. If you were in fact obliged to murder gently, then not murdering would be incompa...

Anarchy is all about public property. Anarchy is socialism without the state.

I think the problematic premise is 1, not 3. It is not the case that we ought to murder gently, for it is the case that we ought not murder at all, wh...

Dark matter and dark energy are posited because we see weird things happening in the universe and posit those names for the as-yet-unknown whatever it...

Yeah, that is a key rule, but I don't think that that is the source of the problem. It's true that if Smith ought to murder Jones gently, that Smith o...

You've got the first part right, but the second part backward. Science is applied philosophy, but philosophy is broader than religion. I would argue t...

I think Virgo was making fun of the grammar of that sentence, which is a little unusual.

Your point about the hidden premise that it’s obligatory to not murder was a key part of my OP.

Coincidentally I came across an old note to myself tonight about this very topic, and I think the conclusion I've now come to upon reading my old thou...

This exactly. When I see black people criticize each other for “acting white”, it looks like they’re being racially prejudiced against their own kind....

What you're describing there is a composite function with the y-value 4 from x-values 1 to 2, and y-value 3 from x-values 3 to 4. In that case it's tr...

Since the functions have non-overlapping domains, they are not simultaneous equations, and x can mean different things for each of them.
